OILING DEVICE FOR FIBER SILK AND THE LIKE.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed October 23, 1919. Serial No. 332,693.

To all/whom t may concern:

Be it known that I, JOSEPH JACOBS, a citizen of the United States, and aresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Oilin Devices for FiberSilk and the like, of w ich the following is a specification.

his invention relates to improvements in oiling devices for fiber silkand the lke.

The object of this invention is to provide any oiling device for fibersilk which may be used in combination with the guiding parts of aknitting machine, and when so einployed, will effectively oil .such silkin its passage from the bobbin to the needles.

Another object of my invention 1s to produce an oiling pot which may bemounted or seated concentrically of the hub of the bobbin rack of themachine'upon the sup porting rod for the concentric guides.

Another object of my inventionis to provide an oiling pad which may beconcentrically-arranged about the hub of aA bobbin rack and with theconventional guide pins above such rack and may be suitably fed withoil.

Another object is to provide such a concentric pad with an oil feed pothaving a cylindrical seat arranged concentrically with the pad andadapted to fit over the supporting rod for the guiding pins and to abutagainst the hub of the bobbin rack so as to enable the positioning ofthe pot and pad intermediate the conventional or standard guide disk andthe bobbin rack to the end that the silk or like yarn may be oiledbefore it reaches the needles.

With these and other objects in view, the invention comprises thecombination' of members and arrangement of parts so combined as toco-act and coperate with each other in the performance of the functionsand the accomplishment of the results herein contemplated, and comprisesin one of its adaptations the species or preferred form illustrated inthe accompanying drawings, in which:

Figure 1 is a side elevation of the upperportion of a knitting machineembodying my invention;

F ig. 2 is a sectional' view of the oil-pot illustrated in Fig. 1; and

Fig. 3 is a plan view of said oil-pot with the oiling-wick and porcelainwick-bed broken away. A

n Referring now to these drawings, which illustrate a preferredembodiment of my invention, 1 1@l indicates supporting legs which extendfrom a suitable b ed plate and base members to a cam-ring 2, with whichis associated the other conventional parts, if necessary, and in whichthe needle-cylinder and needles 2a operate and to which the yarn orthread is fed in the conventional manner. 3 3a indicate suitablesupporting studs for the conventional bobbin rack 4 and dial arch 5..The bobbin ra'ck 4 is, as illustrated, provided with a hub 5a and aguide-pin supporting-rod 6 having guide-pins 7 arranged concentricallyof the hub and supporting rod 6. The rod 6 also has suitably connectedthereto and suitably disposed with relation to the hub and guide pins,the conventional or standardguide-disk 8 having a series of concentricguide-apertures v9. Bobbins l1, provided with raw or unoiled fiber silk,are

mounted concentrically of the hub 5 and rod 6 on spindles 10 and thethreads of liber silk 11a are guided from the bobbin up over theguide-pins 7, thence downwardly through apertures 9 in the guide-disks 8and thence downwardly to suitable thread or yarn guides or carriersassociated with the camring 2 and thence in any conventional way to theneedles 2a.

The foregoing is a description of the conventional knitting machine andin itself forms no art of my invention.

Mounted concentrically of the bobbins and guiding means for the fibersilk threads and intermediate the bobbin and the needles in the path ofmovement of the threads 11, I provide an oiling pad 12 which iscirculail in conformation and is arranged concentrically of the guidepins 7 and of the apertures 9 in the guide-disks 8. As shown, said padforms part of a cylindrical wick 12a and the wick and oiling pad are, asillustrated, supported on the rim 15 of an oil pot 13 provided with anaxial bore 14 cylindrical in conformation and extending from the bottomto the top of the saine. This bore is preferably formed to conform inshape with the rod 6 so as to enable the pot to be fitted over the sameand to enable the seating of the pot concentrically of the bobbins andyarn guides. The pad-supporting rim 15 of the pot 13 preferably extendsoutwardly and downwardly in a curved supporting flange for the oil-pad12. Preferably seated cn the flange 15 to form a I smooth hard bed forthe Wick 12a is a porce- 'of fiber silk or yarn are lain-rin 16 Whichpreferably conforms in shape with the iiange and is seated thereon sothat the pad 12 Will overlie the same. Obviously when the pot 13 isiilled with oil 17 or similar liquid, the wick 12a will by capillaryattraction feed or supply the circular pad 12 with oil and will keep thesame properly moistened, so that when the threads guided into contacttherewith by the standard guide pins 7 and guide disks 8 of theconventional knitting machine, the said silk will, in its passage fromthe bobbin to the needles, be properly oiled; and it is also obviousthat When the circular pad portion of the Wick 12a is Worn out thecylindrical Wick 12a may be moved up and spread over the porcelain bed16 so as to renew the pad, and furthermore that the hard porcelain bedwill prevent Wear on thel Hange'l of the pot 13.

Having described my invention, l claim 1. An oiling device for knittingmachines comprising a cylindrical pot having a vertically-disposed axialbore comprising a cylindrical tube adapted to form a seat for the pot, acircular outwardly-extending marginal flange at the rim thereof as andfor the purpose specified, and means for feeding liquid to said flange.

2. An oiling device for knitting machines comprising a cylindrical pothaving a vertically-disposed axial bore comprising a cylin drical tubeto form a seat 'for the pot, a circular outwardlyextending marginaliiange at the rim thereof and an oiling pad mounted on said rim.

3. An oiling vdevice for knitting machines comprising a. cylindrical pothaving a vertically-disposed axial bore comprising a cylindrical tube toform a seat for the pot, a circular outwardly-extending marginal ange atthe rim thereof and a bed of suitable Wear-resisting material seated onsaid ange as and for the purV ose specified.

4.-. An oiling device for knitting machines comprising a cylindrical pothaving an axial bore comprising a cylindrical tube to form a seat forthe"` pot, a circular outwardly-extending marginal iange at the rimthereof, and a ring of porcelain seated on said flange as and for thepurpose specified,

5. In a knitting machine, the combination `With a bobbin-rack having ahub, a guidepin supportingrod connected with said hub; guide pinssupported on said bariabove and concentrically of said hub; bobbinssupported on said rack having threads supported by said pins,needles'below said rack, anda concentrically arranged oil pad khaving`suitable feeding means and supported in the path of said threads betweenthe bobbins and the needles.

6. In a knitting machine, the combination with a bobbin-rack having ahub, a guidepin supporting-rod connected with said hub; gui-de pinssupported on said bar above and concentrically of said hub; a guide diskhaving apertures on said supporting rod; bobbins supported on said rackhaving threads supported by said pins and guided by said disk apertures;needles below said rack; and a concentrically-arranged oil pad having.suitable feeding means and supported in the path of the said threadsbetiveenthe guide disks and needles.

7. ln a knitting machine, the combination withv a bobbin-rack having ahub, a guidepin supporting-rod connected with said hub; guide pinssupported on said bar above and concentrically of said hub; bobbinssupported on said rack having threads supported by said pins, needlesbelow said rack, l

and an oiling device comprising a cylindrical pot having a boreextending vertically therethrough to form a seating channel for the potmounted on said rod between the bobbins and needles.

ln witness whereof, l have signed my name to t-he foregoingspecification in the presence of tivo subscribing witnesses.
